Saw this mentioned about lockpicking and I thought it would help everyone here:
Look at this picture I found online:
Notice that the circles have colors. Blue and Gray. Depending on which pick you select, it will highlight the corresponding circles to show that it
may apply to them. A gray color means that the pick doesn't work with that specific circle. Therefore, you don't have to waste time wondering if it will work with the gray circles. If all circles are gray, you can skip that pick entirely.
Be careful though for all blues, because that means it can apply to multiple. So you should focus on the ones that have more gray than blue. Having only one blue circle means that's the first one you should focus on figuring out.
